Detailed explanation-1: -QR codes are decidedly more complex and advanced than barcodes, but that’s not surprising given the history of each tool. Barcodes arrived on the scene first, at a time when the processing power of modern computers wasn’t available, so they’re old-fashioned and simple compared to QR codes.
Detailed explanation-2: -They use a square shape and have a much more complex structure than a Barcode. This structure is what makes them extremely error-tolerant, improves their information capacity by a large margin, and makes scanning faster and easier.
Detailed explanation-3: -A quick response code, also known as a QR code, is a type of barcode that includes machine-readable details about the item to which it is attached. A QR code, unlike a standard barcode, is two-dimensional, containing information in both vertical and horizontal directions.
